DeCure for Intellectual disability, autosomal dominant 42

DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for intellectual disability, autosomal dominant 42 — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.

The disease map

Disease moduleIntellectual disability, autosomal dominant 42 maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for intellectual disability, autosomal dominant 42 is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

Molecular view

G protein subunit beta 1 (GNB1)GNB1 is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to

Three unrelated consanguineous families were found with biallelic NSUN6 variants causing an autosomal recessive neurodevelopmental disorder. Two variants are predicted loss-of-function; one leads to absence of NSUN6 via nonsense-mediated decay, the other encodes a misfolded protein. A missense variant in the third family loses enzymatic activity and cannot bind the methyl donor S-adenosyl-L-methionine. Affected individuals show developmental delay, intellectual disability, motor delay, and behavioural anomalies. Drosophila lacking the NSUN6 ortholog have locomotion and learning impairment. This establishes NSUN6 as a cause of autosomal recessive intellectual disability.

A separate case report describes a patient with a heterozygous de novo nonsense c.40C>T (p.Arg14X) variant in TRIP12, classified as pathogenic. This variant was absent from the Human Gene Mutation Database. The patient was diagnosed with autosomal dominant intellectual disability type 42. No other patients or functional data are provided in that report.

A 2022 review notes that intellectual disability affects 1% of the global population and that pharmacological interventions remain limited, partly because of poor understanding of the disorder and a shortage of mouse models. A 2021 review of autosomal recessive intellectual disability emphasises that de novo variants account for most cases in outbred populations, but recessive forms predominate in inbred populations. Neither review reports any drug trial or treatment.

What is still missing: no drug has been tested in either NSUN6- or TRIP12-related intellectual disability. There are no clinical trials, no preclinical pharmacological studies, and no patient stratification beyond the handful of families described. Funding for functional assays, animal model development, and any eventual drug screening has not been reported.

Biallelic variants in NSUN6 cause an autosomal recessive neurodevelopmental disorder

AbstractPURPOSE: 5-methylcytosine RNA modifications are driven by NSUN methyltransferases. Although variants in NSUN2 and NSUN3 were associated with neurodevelopmental diseases, the physiological role of NSUN6 modifications on transfer RNAs and messenger RNAs remained elusive. METHODS: We combined exome sequencing of consanguineous families with functional characterization to identify a new neurodevelopmental disorder gene. RESULTS: We identified 3 unrelated consanguineous families with deleterious homozygous variants in NSUN6. Two of these variants are predicted to be loss-of-function. One maps to the first exon and is predicted to lead to the absence of NSUN6 via nonsense-mediated decay, whereas we showed that the other maps to the last exon and encodes a protein that does not fold correctly. Likewise, we demonstrated that the missense variant identified in the third family has lost its enzymatic activity and is unable to bind the methyl donor S-adenosyl-L-methionine. The affected individuals present with developmental delay, intellectual disability, motor delay, and behavioral anomalies. Homozygous ablation of the NSUN6 ortholog in Drosophila led to locomotion and learning impairment. CONCLUSION: Our data provide evidence that biallelic pathogenic variants in NSUN6 cause one form of autosomal recessive intellectual disability, establishing another link between RNA modification and cognition.

Fragile X Syndrome: An Update on Developing Treatment Modalities

AbstractIntellectual disability (ID; mental retardation) is considered an immutable condition. Current medical practices are aimed at relieving symptoms and not at altering the underlying cognitive deficits. Scientific advancements from the past decade have led to the exciting possibility that ID may now be treatable. Moreover, pharmaceutical therapies targeting the most common form of inherited ID, Fragile X syndrome (FXS), may become the new benchmark for central nervous system (CNS) drug discovery: seeking cures for neurodevelopmental disorders.

[Intellectual disability due to heterozygous c.40C>T variant of TRIP12 gene in a patient].

AbstractOBJECTIVE: To explore the genetic basis for a patient with intellectual disability. METHODS: Whole exome sequencing and Sanger sequencing were carried out for the patient. The result was verified in her family. RESULTS: DNA sequencing revealed that the patient has carried a heterozygous nonsense c.40C>T (p.Arg14X) variant of the TRIP12 gene, which was de novo in origin. The variant was unrecorded in the Human Gene Mutation Database. Based on the American College of Medical Genetics and Genomics standards and guidelines, the variant was predicted to be pathogenic (PVS1+ PS2+ PP3). CONCLUSION: The patient was diagnosed with autosomal dominant intellectual disability due to heterozygous c.40C>T variant of the TRIP12 gene.

Behavioral and brain phenotypes of mouse models of Bardet-Biedl Syndrome

AbstractIntellectual disability (ID) is one of the most common neurodevelopmental disorders, affecting 1% of the population globally. Clinically, ID is characterized by a deficit in intellectual functioning and adaptive functioning. There are limited pharmacological interventions for ID, partially due to a poor understanding of ID and the heterogeneous nature of ID In addition, there are limited mouse models of ID.

Review On Clinical And Molecular Genetics Of Autosomal Recessive Intellectual Disability

AbstractIntellectual disability (ID) is a relatively common phenotype with multiple etiologies. Recent progress in the genetics of ID greatly expanded our understanding of the biological defects underlying this clinical entity. While most published cohort genetic studies on ID revealed the important contribution of de novo (germline or postzygotic) variants, we focused in this study of autosomal recessive ID (ARID), that account for most of the molecular bases in ID cases in inbred populations. We discussed the current state of ARID from a clinical, molecular and genetics standpoints.

An overall review on intellectual disability disorder and its homoeopathic management

AbstractThe Intellectual Disability Disorder is found as a one of the clinical manifestations of the rare disorders which occupies a total prevalence of about 6 to 8% globally. The rare disorder is found to cause many of the chronic disabilities in which the intellectual disability disorder is one of them which has a drastic impact on the individual who is affected and their families and includes the health care system. The onset period of the rare disorder begins from the prenatal period into the late adulthood and it is being assessed that about the half of the individual affected are children [1]. The prime and the only purpose of this study undertaken is to find the effectiveness of the homoeopathic medicine in the treatment of the Intellectual Disability Disorder and also to alter their intellectual and the adaptive functions of the affected individual. The homoeopathic medicine will remove the disease from the root cause.
